My comments on this feature
There are certainly a few key applications for this feature.
One main and obvious application would be to gain access to music, pictures or video held at home from a remote location like the holiday home, car or small business. This would be achieved through the use of technologies like 3G or WiMAX wireless broadband; or simply ADSL broadband depending on the location.
Another application similar to what Barb Bowman was using as her demonstration setup in the articles she had posted on this feature is a household with two or more individually-controlled Internet services. This may be a student or other person who is paying board and lodging to you; a live-in housekeeper or nanny; or an elderly or disabled relative or friend who needs continual care. These people may want to operate a separate Internet service that is under their own control but may want to annexe both the primary household’s and their own media resources.
But. as with any new technical implementation, there are questions that need to be asked
Could this setup work over a VPN such as one used to facilitate remote access to a small business’s data? This setup may be of benefit to a shop or small office where some of the music or pictures used as part of merchandising at the business may be held on the home computer.
Could this allow a UPnP AV / DLNA device to pull up media from the remote location via the Windows Media Player “gateway”? In this setup, a DLNA-compliant Internet radio installed at the remote location points to the UPnP Media Server that is part of the remote computer’s Windows Media Player. This would be pulling up media from the local computer’s Windows Media Player setup as in your described installation.
